I guess it also depends on the severity of the sluggishness. I don't overclock, so any lack of performance I have would probably be unique to my situation. I'm actually not too bothered by the performance, but I do know that it's not as good as it is in Windows, or to put it a better way: It's not as good as it should be based on what the card is. On the other hand, there were guys that I talked to in that other thread who had severe problems with performance and then later found out that they had bad cards. So, really it's up to each person to decide how bad it is and whether it is a problem for them, and what they can do about it. Pretty hard to diagnose something like that otherwise.
